[Swift]UITableView自定義cell

應用入口(AppDelegate.swift)


import UIKit

@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {

    var window: UIWindow?

    func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {

        window = UIWindow(frame: UIScreen.mainScreen().bounds)
        window?.backgroundColor = UIColor.whiteColor()
        
        let viewController = DMViewController()
        let nav = UINavigationController(rootViewController: viewController)
        nav.navigationBarHidden = true
        window?.rootViewController = nav
        
        window?.makeKeyAndVisible()
                
        return true
    }
}

列表控制器(DMViewController.swift)


import UIKit

class DMViewController: UIViewController , UITableViewDelegate , UITableViewDataSource{

    @IBOutlet weak var tableView: UITableView!
    var dataArr = NSMutableArray()
    
    override func viewDidLoad() {
        super.viewDidLoad()
        tableView.delegate = self
        tableView.dataSource = self

        //資料模擬
        for(var i = 0 ; i < 20 ; i++ ){
            let dataDict = NSMutableDictionary()
            //整型->字串
            var title = String(i)
            title.appendContentsOf("abc")

            //浮點->字串
            let double = 20.12
            let doubleString = NSString(format: "%f", double)
            
            dataDict.setObject(title, forKey: "title")
            dataDict.setObject(doubleString, forKey: "double")
            dataDict.setObject(String(i), forKey: "id")
            
            dataArr.addObject(dataDict)
        }

    }

    
    //組數
    func numberOfSectionsInTableView(tableView: UITableView) -> Int {
        return 1
    }
    
    //每組cell數
    func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        return dataArr.count
    }
    
    //賦值
    func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
        /*預設Cell
        let cell:UITableViewCell = UITableViewCell(style: UITableViewCellStyle.Subtitle, reuseIdentifier:"cell");
        cell.textLabel!.text = "test1"
        */
       
        //自定義cell
        let cellIdentifier = "DMTableViewCell"
        self.tableView!.registerNib(UINib(nibName: "DMTableViewCell", bundle:nil), forCellReuseIdentifier: cellIdentifier)
        
        let cell : DMTableViewCell = tableView.dequeueReusableCellWithIdentifier(cellIdentifier, forIndexPath: indexPath) as! DMTableViewCell
        
        if(dataArr.count > indexPath.row){
            cell.assignmentFromDictionary(dataArr.objectAtIndex(indexPath.row) as! NSDictionary)
        }
       
        return cell
    }
    
    //cell高度
    func tableView(tableView: UITableView, heightForRowAtIndexPath indexPath: NSIndexPath) -> CGFloat {
        return 60.0
    }
    
    //選中cell
    func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
        print("選中某個cell");
    }
    
    /**/
    //能否編輯
    func tableView(tableView: UITableView, canEditRowAtIndexPath indexPath: NSIndexPath) -> Bool {
        return true
    }
    
    //cell編輯模式-這裡選擇顯示Delete
    func tableView(tableView: UITableView, editingStyleForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCellEditingStyle {
        return UITableViewCellEditingStyle.Delete
    }
    
    //更改“Delete”為“刪除”
    func tableView(tableView: UITableView, titleForDeleteConfirmationButtonForRowAtIndexPath indexPath: NSIndexPath) -> String? {
        return "刪除"
    }
    
    //對選中的cell根據editingStyle進行操作
    func tableView(tableView: UITableView, commitEditingStyle editingStyle: UITableViewCellEditingStyle, forRowAtIndexPath indexPath: NSIndexPath) {
        if(editingStyle == UITableViewCellEditingStyle.Delete){
            //對資料進行操作
            dataArr.removeObjectAtIndex(indexPath.row)
            
            tableView.reloadData()
        }
    }
}
 

自定義cell(DMTableViewCell.swift)


import UIKit

class DMTableViewCell: UITableViewCell {

    @IBOutlet weak var leftImagview: UIImageView!
    
    @IBOutlet weak var idLab: UILabel!
    
    @IBOutlet weak var titleLab: UILabel!
    
    var dataDict = NSDictionary()
    
    
    override func awakeFromNib() {
        super.awakeFromNib()
        // Initialization code
    }

    override func setSelected(selected: Bool, animated: Bool) {
        super.setSelected(selected, animated: animated)

        // Configure the view for the selected state
    }
    
    //賦值
    func assignmentFromDictionary(valueDict : NSDictionary){
        dataDict = valueDict        
        idLab.text = valueDict.valueForKey("id") as? String
        titleLab.text = valueDict.objectForKey("title") as? String
        
    }
}
